Contributed to composite crashworthiness (a) experimental database, (b) analysis methods, and (c) certification protocols that were developed and ultimately adopted by Boeing and used during certification of the B-787.
Motivation and Key Issues • The matrix-compression material-model used in Abaqus for carbon fiber laminates is computationally efficient but is physically unrealistic and does not correspond to actual material behavior. Objective • Determine the conditions under which the use of this unrealistic material model causes significant errors in predictions of carbon fiber laminate response to […]
